“…Such a correlation is however currently found to be violated in super cooled plastic crystals for unknown reason. 36 Since β is as low as 0.5, caffeine is found to comply with this behavior of plastic crystals. A very interesting feature shown by caffeine which could lead to resolve this violation is the strongly pronounced antiferroelectric local organization of dipoles found when temperature is reaching T g .…”

“…It has been shown that low-temperature phase III of dabcoHBF 4 exhibits structural disorder of protons, similar to that in typical protonic glasses, where the H-atom dynamics in hydrogen bonds is responsible for specific dielectric properties . For example, in the archetypal Rb 1− x (NH 4 ) x H 2 PO 4 (RADP) and similar solid solutions, the dipolar-glass state is achieved by mixing two structurally proximate crystals with competing long-range ferroelectric and antiferroelectric interactions.…”

“…Presently, the group of KDP-type crystals is structurally very diverse and has representatives among inorganic, organic, and hybrid compounds. The proton dynamics is also responsible for the properties of the so-called proton glasses, , produced of two structurally proximate compounds exhibiting competing ferroelectric and antiferroelectric long-range interactions. Most of the studies in the field of H-bonded ferroelectrics and related compounds are concerned with the materials linked by short OH···O hydrogen bonds.…”
